US GDP is expected to grow 2.0% in 2013’s first quarter, according to the latest update of The Capital Spectator’s average econometric nowcast. That’s up slightly from the previous 1.9% nowcast for Q1, which was published on February 5. Today’s nowcast reflects updates to several indicators used for computing the estimates. This year’s official Q1 data is scheduled for release on April 26, when the Bureau of Economic analysis will publish its initial GDP estimate for the first three months of 2013. (GDP percentage changes are quoted as real seasonally adjusted annual rates.)
